Ok guys! I dont know, but the Avatar 410PRO lacks of low end. I dont know what I am doing not getting low end from this rig. I was with my band practicing, and I can get more low end from my Peavey TNT150. 150 Watts, rear ported combo, from the Avater Rig, 1200W. front ported cab. I change the filter to 30hz, change it to 50hz, disable the filter, and I can not get that low end, I am regreting of deciding on 410 than the 212. I dont know if testing the Peavey and the rig, the room or something get that low end from the TNt150 than the Avatar rig.(location of the cab etc, room acoustics) I'll keep you posted, any suggestions?
